## Summary description

The Hager CFA425J is a 4-pole residual current circuit breaker (RCCB) designed for electrical safety. It features a 25A rated current and a 0.3A sensitivity threshold. As a Type A device, it provides protection against both AC and pulsating DC residual currents. This component is essential for preventing electric shocks and protecting electrical installations in residential and commercial distribution boards.

## Long description

The Hager CFA425J is a high-quality 4-pole residual current circuit breaker (RCCB) engineered to enhance electrical safety in various environments. This device is designed to monitor electrical circuits and automatically disconnect power when a residual current is detected, thereby preventing potential electric shocks and mitigating fire risks. With a rated current of 25A and a sensitivity threshold of 0.3A, it serves as a reliable protective component for modern electrical distribution systems.
Advantages
This RCCB stands out due to its Type A classification, which ensures comprehensive protection against both standard alternating current (AC) and pulsating direct current (DC) residual currents. Its robust construction and adherence to strict safety standards make it a dependable choice for long-term installation. The 4-pole configuration allows for versatile application in three-phase systems, ensuring that all conductors are monitored effectively for leakage, which is critical for maintaining the integrity of complex electrical setups.
Suitable for
Residential electrical distribution boards
Commercial building power systems
Protection of circuits with electronic components that may produce pulsating DC leakage
General electrical safety installations requiring 25A capacity
When it may not be suitable
This device is not intended for use in circuits where the load current consistently exceeds 25A, as this would lead to nuisance tripping or potential damage to the unit. Furthermore, it is not designed for direct current (DC) systems or specialized industrial applications requiring Type B protection for smooth DC leakage.
Key specifications
Number of poles: 4
Rated current: 25A
Residual current sensitivity: 0.3A
Type: A (AC and pulsating DC protection)
How to use
The Hager CFA425J must be installed by a qualified electrician within a distribution board or consumer unit. It should be mounted on a standard DIN rail. Ensure that all input and output connections are tightened to the manufacturer's specified torque to prevent overheating. Once installed, the device should be tested using the integrated test button to verify that the tripping mechanism functions correctly under simulated fault conditions.
What to consider before purchase
Verify that the 25A rating is sufficient for your specific circuit load.
Ensure the 0.3A sensitivity is appropriate for the intended application, as this threshold is typically used for fire protection rather than direct human contact protection.
Confirm that your electrical system requires a 4-pole device for three-phase distribution.
Usage recommendations
Regular maintenance is essential for electrical safety. It is recommended to press the test button on the device at least every six months to ensure the mechanical tripping function remains operational. If the device trips unexpectedly, investigate the circuit for insulation faults before resetting.
